Answer:

X = 2

Step-by-step explanation:

\sf \: First, solve  \: the \:  brackets.

\sf \: 10 - 2(2x + 1) = 4(x - 2) \\  \sf10 - 4x - 2 = 4x - 8 \:  \:  \:  \:  \:  \:  \:

\sf \: Combine  \: like \:  terms .

\sf8 - 4x = 4x - 8

\sf \: Subtract  \: 4x \:  from \:  both  \: sides \:  to  \: remove \:  4x.

\sf \: 8 - 4x - 4x = 4x - 8 - 4x \\  \sf8 - 8x =  - 8

\sf \: Subtract  \: 8 \:  from  \: both \:  sides \:  to  \: remove \:  8.

\sf8 - 8 - 8x =  - 8 - 8 \\  \sf - 8x =  - 16

\sf \: Divide  \: both  \: sides \:  by \:  -8.

\sf \: x = 2

What is the length of JK¯¯¯¯¯, to the nearest tenth of a millimeter? 4.5 mm 5.6 mm 8.3 mm 19.9 mm A horizontally-aligned scalene
Leokris [45]

Answer:

5 = side a

3 = side c

angle B = 62 degrees

JK is side b

Use the Law of Cosines to find the length of side b.

b^2 = a^2 + c^2 − 2ac cos(B)

b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)

b^2 = (25 + 9) − 30 x 0.469

b^2 = 34 - 30 x 0.469

b^2 = 34 - 14.084

b^2 = 19.916

b = √19.916

b = 4.463

Rounded to the nearest tenth is 4.5 mm.

Hope this helps!
